20150292702 | Rotary Electromagnetic Actuator and Car Lamp Low Beam and High Beam Light Switching Device Thereof - A rotary electromagnetic actuator and a car lamp low beam and high beam light switching device. The rotary electromagnetic actuator, comprising a shell, a rotor, a stator, a rotating shaft and an end cover; a stator winding is arranged on the stator, and the stator is fixedly installed at the inner part of the shell to form a pair of arc-shaped stator magnetic poles on which electric excitation can be applied; the rotor, as an arc-shaped permanent magnet, is fixed on the rotating shaft and is located in a magnetic field space of the arc-shaped magnetic poles of the stator; and the rotor is matched with the arc-shaped stator magnetic poles to form an air gap closing magnetic path; an swing bar extending along radial direction of the rotating shaft is connected to two ends of the rotating shaft respectively; the light screen of the car lamp low beam and high beam light switching device is fixedly connected on the swing bars at two ends of the rotating shaft; and a swing angle of the light screen is identical with a rotating angle of the rotor. | 10-15-2015 |
20110277263 | Vehicle Headlight Cleaning Apparatus - The invention relates to a vehicle headlight cleaning apparatus. A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. Both ends of the spring are respectively fixed on the end part of the cleaning apparatus and a spring fixing seat of the movable seal valve. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. The pressure of the cleaning solution increases continuously, then the movable seal valve is opened under the pressure of the cleaning solution, the cleaning solution sprays out through the transmission guide rod and the nozzle, and a complete cleaning circuit is formed. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring, the transmission guide rod retracts into the casing till to an initial position, and the whole cleaning is finished. The invention has small and exquisite appearance, light weight, reliable work and high cleaning efficient. | 11-17-2011 |
